Rejuran — Korean Polynucleotide (PN) Skin Booster

Korean polynucleotide injection from purified salmon DNA — wound-healing-grade biorestoration, popular with Korean and Japanese visitors. NOT halal — see substitution map.

What is Rejuran?
Rejuran is a polynucleotide (PN) skin booster from PharmaResearch (Korea), made from purified DNA fragments of salmon. Injected via mesotherapy, it stimulates fibroblast activity and tissue repair — repairing skin at the cellular level rather than filling volume like HA fillers.

Rejuran is a polynucleotide (PN) skin booster from PharmaResearch (Korea) — purified salmon DNA fragments delivered via mesotherapy injection to stimulate cellular regeneration, fibroblast activation, and skin barrier repair. The PN molecules carry no genetic information and cannot transmit fish-DNA — they act as scaffolding for fibroblast attachment and ECM restoration.

Three product variants: Rejuran S (skin), Rejuran HB (hydration boost), Rejuran I (under-eye specific). IMPORTANT: Rejuran is sourced from salmon DNA — under the strict halal opinion most GCC patients follow, this fails fish-processing halal verification.

Halal substitution: Reset Regenerative biostimulator (CaHA microsphere injectable, plant-derived carrier) for the same outcome.

الأصالة والمصدر

من أين، ما المكونات، ومن يعتمدها

غير حلال

حمض نووي السلمون / متعددات النيوكليوتيدات (PN). السلمون مصدر محل خلاف في الرأي الحنفي (يُسمح فقط بـ'الأسماك ذات القشور'، واستخراج الحمض النووي محل جدل). غير حلال وفق الرأي المتشدد الذي يتبعه أغلب مرضى الخليج.

أسئلة شائعة
Is Rejuran halal?+
No, under the strict halal opinion most GCC patients follow. Rejuran is purified salmon DNA — fish-DNA halal status is contested between schools (lenient opinion accepts fish by default; strict opinion requires fish-processing verification). The standard salmon-DNA injectable supply chain does not document halal-compliant fish processing. We classify Rejuran as not halal under the strict interpretation. Halal substitution: Reset Regenerative biostimulator for cellular regeneration, or Profhilo for skin-barrier restoration.
Which Rejuran variant is right for me?+
Rejuran S — standard skin booster, acne scars, general skin renewal. Rejuran HB — adds hyaluronic acid for hydration emphasis; popular for dehydrated mature skin. Rejuran I — formulated for the delicate under-eye area, smaller injection volume per point. Your physician will map your skin concern to the right variant; many patients use S + I in combination on the same visit.
Why do my friends in Korea use Rejuran specifically?+
Korean aesthetic culture has familiar trust with Rejuran — PharmaResearch is a Korean company, and Rejuran has been a Korean clinic standard since 2014. Most Korean visitors specifically request Rejuran by name. We honour that brand-trust by using identical Korean-source product, supplier-verified, with the same clinical protocols Seoul clinics use. Patients who experienced Rejuran in Seoul receive the equivalent product here.
Rejuran Healer vs Rejuran S — what's the difference?+
Rejuran Healer is the ORIGINAL product (launched 2014, PharmaResearch Korea) — the foundational polynucleotide formulation. Rejuran S is the SECOND-generation upgrade (launched 2018) with higher PN concentration and improved viscosity, specifically optimised for ACNE SCARS and atrophic depressions. They share the same active mechanism (salmon-DNA polynucleotides) but Rejuran S delivers a stronger remodelling signal at scarred sites. At Waleerat, we recommend Rejuran S for visible acne scarring + dermal-thickness loss, Rejuran Healer for general skin-quality maintenance, and Rejuran I for the under-eye specifically. Pricing identical at ฿6,500/ampoule across all three variants.
What is a Rejuran injection? How long does it take?+
A Rejuran injection is a meso-style injection of polynucleotide (PN) — small-volume dermal injections placed across the treatment area (face, neck, under-eye) using a 30G or finer needle (or microneedle stamp for facial coverage). One full-face session takes 30-45 minutes including topical numbing. The polynucleotides settle into the dermis where they stimulate fibroblast activity and tissue repair over the following 4-6 weeks. The full Rejuran program is typically 3 sessions spaced 2-4 weeks apart; effects build progressively over 12 weeks and last 6-12 months.
